Questions
How big is the Rocky ctrl PCB?
It measures 93 × 155.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Rocky ctrl use?
173 parts, built around the SN74LV1T125DBV, CH340C, ESP32-WROOM-32E-N8 and AP63203WU. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Rocky ctrl KiCad files?
From the PotatoPeaSea/Rocky repository on GitHub, at the commit this page was made from: the board is pcb/rocky_ctrl/rocky_ctrl.kicad_pcb and its schematic pcb/rocky_ctrl/rocky_ctrl.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rocky ctrl design in my own project?
Its repository states no licence, so its author keeps all rights: ask PotatoPeaSea before reusing the design.
